[safe-output-health] 🏥 Safe Output Health Report — 2026-06-10

[github-actions[bot]]

Executive Summary

Ninth consecutive clean day. Across the 24h window (60 run directories, 01:54Z–05:44Z), zero safe-output jobs failed and zero safe-output messages failed at actuation. Every audited real-write job succeeded — 5 create_issue, 2 create_discussion, 3 add_comment, 1 update_pull_request, plus 5 noop. The 100% safe-output job success streak now runs 2026-06-01 → 2026-06-10 (audit gap on 06-08 only).

One in-scope, non-fatal observation: Issue Monster emitted 3 assign_to_agent messages rejected at collection-time validation for missing the required issue_number/pull_number field. The job still concluded success (the paired add_comment messages actuated), but the 3 intended Copilot assignments were silently dropped before actuation.

• Period: Last 24h (2026-06-10 01:54Z–05:44Z)
• Runs analyzed: 60 run directories (~25 distinct workflows)
• Safe-output jobs (audited): 10 success + 2 by-design no-findings skips + 4 agent-failure skips
• Safe-output job hard failures: 0
• Message actuation failures: 0
• Collection-time validation rejections: 3 (Issue Monster assign_to_agent)
• Run-level safe-output job success rate: 100%

Safe Output Job Statistics

Job / message type	Audited	Actuation failures	Notes
create_issue	5	0	Sergo ×2, LintMonster ×3
create_discussion	2	0	Sergo, LintMonster
add_comment	3	0	Issue Monster (#38269/#38270/#38271)
update_pull_request	1	0	PR Description Updater (#38263)
noop	5	0	Step Name Alignment, Avenger, Design Decision Gate, PR Sous Chef, LintMonster
assign_to_agent	0 actuated	n/a	3 rejected at collection-time (missing issue_number/pull_number)
review-comment / submit_review	0	0	Not exercised — reviewers found nothing

Metrics blind spot (recurring): the aggregator reported write_runs=1 / total_safe_items=1 despite ~11 real writes succeeding. The single counted item is the Release run's upload_asset manifest. Same actuation-metric undercount first logged 2026-05-31. Cosmetic only.

Critical Issues

None. No safe-output job hard-failed and no message failed at actuation.

New In-Scope Finding (Low–Medium)

assign_to_agent_missing_issue_pull_number_collection_rejected

• Run: §27251903334 — Issue Monster
• What happened: 3 add_comment messages (issues [lint-monster] chore: Function length refactoring (645 functions exceed 60-line limit) #38269/[lint-monster] chore: Replace map[string]bool with map[string]struct{} (152 instances) #38270/[lint-monster] chore: Fix context propagation and os.Setenv (11 issues) #38271) announcing "requested assignment to the Copilot coding agent" actuated fine, but 3 paired assign_to_agent messages were rejected during collection-time validation:

  Line 1/2/3: assign_to_agent requires at least one of: 'issue_number', 'pull_number' fields
  

• Root cause: The assign_to_agent messages carried no issue_number/pull_number — most likely they reused the item_number field (which add_comment accepts but assign_to_agent does not).
• Impact: Net actuation Failed: 0, job success. However the 3 Copilot assignments never actuated, and the posted comments now misrepresent that an assignment was requested.
• History: Same handler/family as the 2026-05-31 cluster assign_to_agent_literal_issue_number_guess_unresolved, but a different failure stage — 05-31 guessed wrong issue numbers and failed at actuation; today omitted the required field and was dropped at collection-time validation.

Out-of-scope agent-job failures (5) — for completeness

All 5 agent-job failures in the window are out of scope (other monitors own them):

Run	Workflow	safe_outputs job
§27253757407	Code Simplifier	skipped
§27251189140	Daily Community Attribution Updater	skipped (empty output, failed pre-activation)
§27250878325	Daily Firewall Logs Collector	skipped
§27250116418	Daily Ambient Context Optimizer	skipped (empty items:[])
§27251417279	Avenger	success — clean noop handoff despite agent failure

Healthy signal: Avenger's agent job failed (intermittent API unreachability + sandbox tmpfs test artifact), yet it emitted a clean noop the safe-output job processed successfully — failure-path handoff stayed healthy (same pattern noted 2026-06-06).

Recurring Cluster Status

All tracked clusters latent or healthy today

Cluster	Status today
review_path_unresolved_422	Not exercised — PR #38284 reviewers found nothing; jobs skipped. Path-variant fallback (pr_review_buffer.cjs:554) UNVALIDATED 13th consecutive audit.
assign_to_agent_literal_issue_number_guess_unresolved	Related variant exercised — see new finding above (collection-time, not actuation).
target_star_review_comment_no_pr_number_fallback	Not exercised.
target_star_add_comment_no_item_number_fallback	Not exercised — Issue Monster comments carried resolvable item_number.
cancellation_counter_mislabeled_code_push_failed	Not exercised (no WTD3 abort).
own_pr_review_event_422_retry_comment	Not exercised.
push_branch_protection_check_403_nonfatal	Not exercised.

Recommendations

1. (Low–Med) Harden assign_to_agent against the missing-field variant.
   • Agent-side: Issue Monster should emit assign_to_agent with issue_number (or an #aw_ temporary-id), not item_number.
   • System-side (optional): accept item_number as an alias for issue_number on assign_to_agent (parity with add_comment); and/or gate the "selected for Copilot" comment on the assign_to_agent succeeding, so a comment never claims a dropped assignment.
2. (Low) Validate the review_path_unresolved_422 Path-variant fallback. The pr_review_buffer.cjs:554 predicate fix is unvalidated for the 13th consecutive audit — no 422 has fired since 2026-05-27. Happy path healthy; recovery path never executed. Consider a smoke that forces a Path could not be resolved 422.
3. (Cosmetic) Reconcile the actuation-metric undercount (write_runs/total_safe_items).

Work Item Plans

WI-1 — assign_to_agent field-resolution hardening (Bug/ergonomics, Medium, Small effort): resolve item_number/#aw_ → issue_number on assign_to_agent (or fix Issue Monster's emitted field), and gate the "selected for Copilot" comment on assignment success. Acceptance: regression test for an assign_to_agent carrying only item_number; comment only posts when assignment actuates.

WI-2 — force-exercise the review 422 Path-variant fallback (Test coverage, Low, Small effort): inject a Path could not be resolved 422 and assert the body-only fallback fires and recovers.

Historical Context & Trends

• Streak: 9 consecutive clean days (06-01 → 06-10); the only failures this window are out-of-scope agent-job failures.
• Error-rate trend: Stable at 0 hard failures. Collection-time rejections ticked 0 → 3, all from one workflow's assign_to_agent field usage.
• Watch item: the assign_to_agent cross-reference family has now surfaced in 2 distinct stages (actuation guess-failure 05-31; collection-time missing-field 06-10).

Metrics & KPIs

• Overall safe-output job success rate: 100% (0 hard failures)
• Message actuation failure rate: 0%
• Collection-time validation rejections: 3 (all assign_to_agent, one workflow)
• Most problematic handler: assign_to_agent (only handler with dropped messages — at validation, not actuation)

Next Steps

• Route WI-1 (assign_to_agent field resolution + comment gating).
• Keep watching the assign_to_agent family for a 3rd-stage variant.
• Track the review_path_unresolved_422 Path-variant fallback until it actually fires.
